DCN example 3 - Using single OME6130 GNE with OSPF to external DCN.
OSPF is used in between OME6130 network elements.
In this example (see
10-37), a single OME6130 network element is used as the GNE to establish
communication between the external DCN and the OME6130 sub-system.
OSPF routing protocol is used in between the OME6130 GNE and the external
DCN router, and in between the OME6130 network elements using IP over
DCC.
The external DCN router connected to the OME6130 GNE is acting as an Area
Border Router (ABR) which can use the route summarization feature to group
the IP routes for the OME6130 sub-network into a single route covering all the
OME6130 Router ID IP addresses.
This example does not provide redundant access to the OME6130 sub-system
from the external DCN because only one OME6130 NE is connected to the
external DCN. However, the DCC between the OME6130 NEs is redundant.
